Did my mail imply that bandwidth is the issue?(well maybe) however If a
root server is as close as possible wouldn't latency be relatively better.
I have explained the mobile to ISP to name server scenario in my pervious
mail.

Maybe you should tell me the cost you are referring to which made you drop
your root server in Australia as I think this still comes down to bandwidth
required to serve the rest of the world.

the beginning but not the end of the discussion.  The technical question is
whether a locale is being served well enough.  "Well enough" is usually
measured in terms of delay to get an answer to a look up, e.g. 89
milliseconds, and reliability, e.g. answers are received 99.923% of the
time.  (Both of the numbers in the previous sentence are illustrative and
not related to any actual measurement.  I made them up as I typed.)  On the
other hand, many people seem concerned with political questions, e.g. which
countries are important enough to have root servers.  It would help the
discussion to know what questions are being asked.  The list of root server
locations may or may not be relevant.
